Because some functions are often called, they are written separately and concentrated in a separate PHP file. The other calls to the page will be required called. The problem is that
1. Will this be called by other websites?

2. How do I disable direct access to PHP?

3. How should file permissions be set??
Does someone else access my PHP operation via PHP is the "World" "Run" permission?

------Solution--------------------
1. No. Unless your php.ini allow_url_fopen is set to open
2. How do I disable access to PHP? You can place PHP files in a directory outside the web directory
3. Sorry not to understand, in addition to distinguish Win/linux system
------Solution--------------------
1. If not on the same server, others cannot require to your function, remote include can only get the content you output, if all is a function, that is blank. And you can go through the. htaccess or put it in a web directory to prevent other people from accessing
